Mass of a planet is `(1)/(9)` of the mass of the earth.The radius of the planet is `(1)/(2)` that of the earth.If the man weight 9N on the earth,his weight on the planet is
(A) 1N
(B) 4N
(C) 6N
(D) 5N

If mass of the planet is 10% less than that of the earth and radius of the planet is 20% greater than that of the earth then the weight of 40kg person on that planet is

If mass of the planet is "10%" less than that of the earth and radius of the planet is "20% greater than that of the earth-then the weight of "16kg" person on that planet is

The mass of a planet is six times that of the earth. The radius of the planet is twice that of the earth. It's the escape velocity from the earth is v , then the escape velocity from the planet is:

A planet has double the mass and double the average density of the earth. If the weight of an object on the earth is 100 N, its weight on the planet will be

The mass of a planet is half that of the earth and the radius of the planet is one fourth that of the earth. If we plan to send an artificial satellite from the planet, the escape velocity will be (V_(e)=11 kms^(-1))

The mass of planet is 1/64 of the earth but the gravitational pull is 1/9 of the earth. It is due to this reason

The mass of a hypothetical planet is 1/100 that of Earth and its radius is 1/4 that of Earth. If a person weighs 600 N on Earth, what would he weigh on this planet?

If the density of the planet is double that of the earth and the radius 1.5 times that of the earth, the acceleration due to gravity on the planet is

If the mass of a planet is 10% less than that of the earth and the radius is 20% greater than that of the earth, the acceleration due to gravity on the planet will be

The mass of planet mars is 1/10 th of the mass of earth and radius is 1/2 of the radius of earth. If the scape velocity at the earth is 11.2km/s, then the scape velocity at Mars will be
